The women's singles between fifth seeded Japanese Nozomi Okuhara and Sun Yu of China transfixed the stadium. They had played six times previously since the 2012 World Junior Championships and split the victories evenly but it was Okuhara's to relinquish as she's been one of the two hottest players in this discipline since the end of 2015.
There was a marked difference between the Okuhara of 2015's Australian Open and a year later. She no longer resembled the national style of running at top speed to retrieve shuttles but produced clever changes of pace in dictating the play.
Sun Yu, a Superseries winner herself, possessed the obvious weapons of her height and extra reach. In the tense closing stages of the deciding game, Sun patiently kept an eye out for the mid-rally opportunities at the rear court to be able to produce the sharpest of outright cross court winners.
Okuhara could have made it to deuce but overhit into the net a sitting duck net shot she had worked so hard to make construct thus giving the match to her Chinese opponent 21-23, 21-17, 21-19.
In mixed doubles, Maiken Fruergaard / Anders Rasmussen were the second Danish pair in the space of a week to remove former World Champions Liliyana Natsir / Tontowi Ahmad of Indonesia early on in a Superseries, 21-12, 18-21, 21-15.
The defence of the Danes was frustratingly solid especially Fruergaard's and it largely killed the rhythm and creativity of their top seeded opponents.
The large and loud singalong Indonesian fanbase cheered Anthony Ginting on to an un-self conscious performance full of deception that was enough to overcome men's singles seventh seed Chou Tien Chen of Taiwan in straight games. 21-8, 21-12.
